> Specifically, would you actually prefer to see people as individuals whose only goal is maximizing their personal interests, all else be damned? Should they exploit every interpersonal relationship and externalise every negativity in their selfish-driven mandate? Should short-term personal wants trump long term anything?

People are already pretty selfish, and without any regulation and oversight they will definitely act in ways that are detrimental to society. That's why we have laws and law enforcement.

The only difference from corporations is that people do not only pursue money. They may have different goals (sex, pleasure, power, influence). That makes people notoriously difficult to parse, and dealing with them is extremely frustrating.

Corporations are easy, they are the incarnation of greed. For them money is all that matters.
